Molecular sieves
Precise drying and selective separation
Molecular sieves are high-performance adsorbents whose precisely defined pore sizes enable the selective adsorption of molecules . They are ideal for drying, purifying and separating gases and liquids – both in the laboratory and in industrial applications.
Thanks to their crystalline structure (typically zeolites), molecular sieves offer very high adsorption capacitythermal stability and reusability. This makes them a reliable solution for processes in which moisture or specific contaminants need to be removed safely and in a controlled manner.
We stock molecular sieves in all standard types – 3A, 4A, 5A and 13X – each with specific pore sizes and properties tailored to different requirements. Whether for drying solvents, gas treatment, CO₂ removal or moisture control in technical systems, our molecular sieves deliver consistent performance and high purity.
For dry, stable and efficient processes.

FAQ
These are crystalline adsorbents (usually zeolites) with precisely defined pore sizes. They can selectively absorb certain molecules and exclude others – making them ideal for drying and separation.
We offer 3A, 4A, 5A and 13X.
They differ in pore size and, consequently, in the type of molecules they can adsorb.
They are used, among other things, for:
- in the drying of gases and solvents
- in air and gas treatment
- during the removal of CO₂ and H₂O
- for moisture control in cooling and hydraulic systems
- in the petrochemical industry and in chemical synthesis processes
Yes. They can undergo many adsorption and regeneration cycles without losing their performance – provided they are used correctly.
The choice depends on the molecular size, the desired degree of drying, the medium (gas or liquid) and the process conditions.
